I can't recall if she was licking herself right before or not, but I'll see if she does that if she ever air humps again.
I thought her recent peeing habits was strange. She'll hold it in for hours and not because she's forced to do or anything. She just doesn't ask to go out and when I do let her out, she doesn't always go. Then some days, she'll pee back to back in a short amount of time. I've only noticed this on weekends. Idk what she does on weekdays when she is home with my parents. They say she asks to go out a lot, but they just let her out in the yard. Since they don't go out with her, they don't know if she actually goes or not.
I think humping can be a sign of a UTI. If it's burning them or itchy.
